Ventilation
There are vents and fan openings on the front and the rear of the server. These openings
are designed to allow
airflow,
which prevents the server from overheating.
Note:
At least four inches of clearance must be present at the rear of the
server rack so that
airflow
is unrestricted.
Caution:
Do not place the server in a built-in installation unless proper ventilation is
provided.
Do not operate the server in a cabinet whose internal ambient temperature
exceeds 35º C (95º F).
Server front panel
The front of these servers feature a removable bezel that shields the front-facing server
components.
